Curious if this is anomalous behavior. When I just run the motor (SSS 500KV 56104) and the attached gearbox (5:1) in air at modest rpm - the gearbox gets warm and then hot to the touch very quickly. I haven’t timed it, but certainly if it runs for 2 minutes it is generating a fair amount of heat. The motor is only pulling 2.5 amps, so no load at all. Gearbox is brand new, purchased from the manufacturer.
Do all gearboxes get this hot? Am I supposed to lubricate it in some way that I don’t know about? Thanks in advance - Adam
